CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a National Stage of International Patent Application No. PCT/CN2017/112722 filed on Nov. 23, 2017, which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

This application relates to the field of electronic technologies, and in particular, to a photographing method and a terminal.

BACKGROUND

With the progress of society and improvement of people's living standard, more people choose to use photographs to record details of life. For example, a user may tap a “Camera” application icon on a home screen of a mobile phone to control the mobile phone to turn on a camera and display a photographing interface.

When the mobile phone currently displays an interface of another application (for example, WeChat), the user needs to control the mobile phone to exit the currently displayed application interface and display the home screen of the mobile phone, and then taps the “Camera” application icon on the home screen of the mobile phone to control the mobile phone to turn on the camera and display the photographing interface. User operations such as controlling the mobile phone to exit the current application interface and return to the home screen of the mobile phone and then tapping the “Camera” application icon to start the “Camera” application are complex, and human-machine interaction performance is relatively poor.

SUMMARY

This application provides a photographing method and a terminal, to simplify user operations for starting a “Camera” application on the terminal, improve human-machine interaction performance of the terminal, and further improve user experience.

According to a first aspect, this application provides a photographing method, which may be applied to a terminal including a camera and one or more sensors, where the one or more sensors are configured to detect a status of holding the terminal by a user, and the photographing method includes: displaying, by the terminal, a first interface, and displaying a first photographing control on the first interface in response to detecting that a current status of holding the terminal by the user undergoes a change satisfying a preset condition, where the first interface is not a viewfinder interface of the terminal; and displaying a second interface on the terminal in response to an operation of the user on the first photographing control, where the second interface is a viewfinder interface of the terminal.

When the terminal displays the first interface (that is, an interface when the terminal is in a screen-on state), and detects that the status of holding the terminal by the user undergoes the change satisfying the preset condition, the terminal displays, on the first interface, the photographing control used to turn on the camera, so that the user can operate the photographing control to start a “Camera” application for photographing. When the terminal displays the first interface, and automatically detects that the status of holding the terminal by the user undergoes the change satisfying the preset condition, the terminal displays, on the first interface, the photographing control used to turn on the camera, so that the user can operate the photographing control to start the “Camera” application for photographing. This can simplify user operations for starting the “Camera” application on the terminal, improve human-machine interaction performance of the terminal, and further improve user experience.

It may be understood that, the user may want to record some fleeting images, but in a process in which the terminal displays the first interface and displays the second interface after interacting with the user, the images that the user wants to shoot possibly no longer exist, and user experience is affected.

On this basis, in a possible design, when the terminal displays the first interface, the terminal may turn on the camera in the terminal in response to detecting that the current status of holding the terminal by the user undergoes the change satisfying the preset condition, to capture a preview image by using the camera.

In this design, when the terminal displays the first photographing control on the first interface, even if the terminal turns on the camera to capture the preview image, a viewfinder frame of the camera is not displayed on the first interface, that is, the first interface is not a viewfinder interface of the terminal. In other words, even if the terminal has turned on the camera for viewfinder setting and photographing, because the terminal does not display the viewfinder interface, the user cannot see, on a display screen of the terminal, the image captured or taken by the terminal by using the camera.

In another possible design, the terminal may turn on the camera when displaying the first photographing control on the first interface. Because the terminal has turned on the camera when displaying the first interface, and has captured the preview image by using the camera, the terminal may save, in response to the operation of the user on the first photographing control on the first interface, a first image obtained based on the preview image, and display the second interface.

Specifically, the displaying a second interface on the terminal in response to an operation of the user on the first photographing control includes: saving, in the terminal in response to a first operation of the user on the first photographing control, a first image obtained based on the preview image, and displaying the second interface on the terminal. The first operation may be a tap operation, a touch and hold operation, a double-tap operation, a slide-up operation, or a slide-down operation.

Optionally, when the first operation is a different operation, the first image may be different image content. For example, when the first operation is a slide-up operation of the user on the first photographing control, the first image saved by the terminal may be an image whose definition is the highest in the preview images captured by the camera; or when the first operation is a slide-down operation of the user on the first photographing control, the first image saved by the terminal may be a video image including a plurality of preview images captured by the camera.

In another possible design, the one or more sensors may determine, by detecting that the terminal is rotated, or that the terminal moves forward relatively to the user, or that the terminal moves upward relatively to a horizontal line, whether the status of holding the terminal by the user undergoes the change satisfying the preset condition.

Specifically, the terminal may detect a motion parameter of the terminal; then determine, based on the motion parameter, whether the terminal is rotated, or whether the terminal moves forward relatively to the user, or whether the terminal moves upward relatively to the horizontal line; and finally determine, based on a determining result, whether the status of holding the terminal by the user undergoes the change satisfying the preset condition. For example, when the motion parameter detected by the sensor in the terminal indicates that the terminal is “rotated”, “moving forward”, and “moving upward”, the first photographing control may be normally displayed; or when the motion parameter detected by the sensor in the terminal indicates that the terminal is “rotated”, “moving forward”, and “moving upward, but an upward amplitude is insufficient”, the first photographing control may be normally displayed but is relatively small, and transparency of the first photographing control is relatively high.

In another possible design, that a current status of holding the terminal by the user undergoes a change satisfying a preset condition specifically includes: an included angle between a display screen of the terminal and a horizontal screen line is within a preset range after the one or more sensors detect that the terminal is rotated and moves upward

In another possible design, when the operation (that is, a second operation) of the user on the first photographing control may be a different user operation such as a tap operation, a double-tap operation, or a touch and hold operation, the second interface may also be a photographing interface in a different photographing mode of the terminal. To be specific, the second interface is a photographing interface of the terminal in a photographing mode corresponding to the second operation. Photographing modes of the terminal may include at least a photographing mode using a rear-facing camera, a self-photographing mode, a panoramic mode, and a video mode. Specifically, the displaying a second interface on the terminal in response to an operation of the user on the first photographing control may include: displaying, on the terminal in response to a second operation of the user on the first photographing control, a viewfinder interface in a photographing mode corresponding to the second operation.

The terminal may display viewfinder interfaces in different photographing modes in response to different operations of the user on the first photographing control. Therefore, the user can control, by performing different operations on the first photographing control, the terminal to directly display a corresponding viewfinder interface, and does not need to control the terminal to switch between photographing modes after controlling the terminal to display the viewfinder interface for photographing by the rear-facing camera.

In another possible design, the second interface includes a second photographing control. After the displaying a second interface on the terminal in response to an operation of the user on the first photographing control, the method in this application further includes: saving, in the terminal in response to a third operation of the user on the second photographing control, an image captured by the camera in response to the third operation.

Optionally, to facilitate user operations, when a left hand of the user holds the terminal, the terminal may display the second photographing control in a high-frequency touch area on a left side of the second interface, or when a right hand of the user holds the terminal, the terminal may display the second photographing control in a high-frequency touch area on a right side of the second interface.

In this application, the terminal may display, on the second interface, the second photographing control used to control the terminal to perform photographing, and the second photographing control may be displayed on one side on which the user holds the terminal, so that the user can operate the second photographing control more conveniently and comfortably. This can avoid a problem that a single hand of the user cannot conveniently tap a shutter of the terminal for photographing when a touchscreen of the terminal is relatively large, and can improve user experience.

In another possible design, after the displaying a second interface on the terminal in response to an operation of the user on the first photographing control, the method in this application further includes: displaying a third interface on the terminal in response to a fourth operation of the user on the second photographing control, where the fourth operation is used to instruct the terminal to switch between photographing modes of the terminal, the third interface is a viewfinder interface of the terminal in a photographing mode corresponding to the fourth operation, and the fourth operation is different from the third operation.

The terminal may switch between the photographing modes of the terminal in response to the fourth operation of the user on the second photographing control. This improves efficiency of switching between the photographing modes of the terminal by the user, and improves user experience.

In another possible design, display positions of the first photographing control and the second photographing control on the display screen of the terminal are the same.

In another possible design, the terminal may display, in a floating manner, the first photographing control on the first interface displayed by the terminal. Therefore, the terminal can display, on the first interface in response to a moving operation of the user on the first photographing control, dynamic images of the first photographing control that dynamically moves along a moving track of the moving operation.

In another possible design, after the terminal displays the first interface including the first photographing control, if the terminal does not receive the first operation of the user on the first photographing control within a preset time, it indicates that an operation of holding the terminal by the user may be an unintentional operation of the user. To prevent the terminal from displaying the first photographing control on the first interface due to an unintentional operation of the user, the terminal may display the first photographing control that gradually scales down, until the first photographing control is not displayed. Specifically, the method in this application may further include: after the displaying, in a floating manner, the first photographing control on the first interface displayed by the terminal, if no operation on the floating first photographing control is detected within a preset time, no longer displaying the first photographing control on the first interface.

In another possible design, the displaying, by the terminal when displaying a first interface, a first photographing control on the first interface in response to detecting that a current status of holding the terminal by the user undergoes a change satisfying a preset condition includes: when the terminal displays the first interface, displaying, by the terminal, the first photographing control on a left side of the first interface in the floating manner in response to detecting that the terminal is currently held by the left hand of the user, or displaying the first photographing control on a right side of the first interface in the floating manner in response to detecting that the terminal is currently held by the right hand of the user.

The terminal may display the first photographing control on the left side of the first interface when the left hand of the user holds the terminal, or display the first photographing control on the right side of the first interface when the right hand of the user holds the terminal, so that the user can operate the first photographing control more conveniently and comfortably, and user experience can be improved.

In another possible design, before the displaying a first photographing control on the first interface of the terminal, the method in this application further includes: detecting that the camera is in an off state. To be specific, the first photographing control is displayed on the first interface only when the camera is in the off state. If the camera is in an on state (for example, when the terminal turns on the camera for photographing), even if the terminal detects that the current status of holding the terminal by the user undergoes the change satisfying the preset condition, the terminal does not display the first photographing control.

In a possible design, the terminal further includes a turn-on unit, where the turn-on unit is configured to: when the terminal displays the first interface, turn on the camera in response to detecting, by the detection unit, that the current status of holding the terminal by the user undergoes the change satisfying the preset condition, to capture a preview image by using the camera.

In another possible design, the terminal further includes a storage unit, where the storage unit is configured to save, in response to a first operation of the user on the first photographing control, a first image obtained based on the preview image.

According to a tenth aspect, this application provides a communication method, which may be applied to a terminal including a left antenna and a right antenna, where the left antenna is disposed on a left part of the terminal, the right antenna is disposed on a right part of the terminal, and the method in this application includes: in a voice communication process of the terminal, detecting a current status of holding the terminal by a user; and when the current status of holding the terminal by the user is a state of holding the mobile phone by a left hand, increasing transmit/receive power of the right antenna; or when the current status of holding the terminal by the user is a state of holding the mobile phone by a right hand, increasing transmit/receive power of the left antenna.

In this application, the terminal may determine, in the voice communication process of the terminal, the status of holding the terminal by the user; and when the status of holding the terminal by the user is the state of holding by the left hand, considering that the left antenna may suffer relatively great interference, to ensure that voice communication quality of the terminal is not affected, the transmit/receive power of the right antenna may be increased; or when the current status of holding the terminal by the user is the state of holding by the right hand, considering that the right antenna may suffer relatively great interference, to ensure that voice communication quality of the terminal is not affected, the transmit/receive power of the left antenna may be increased.

In a possible design, when the status of holding the terminal by the user is the state of holding by the left hand, the left antenna may suffer relatively great interference; or when the status of holding the terminal by the user is the state of holding by the right hand, the right antenna may suffer relatively great interference. Therefore, if one antenna of the terminal suffers relatively great interference, to reduce power consumption of the terminal, the terminal may reduce transmit/receive power of the antenna. Specifically, after the detecting a current status of holding the terminal by a user in a voice communication process of the terminal, the method in this application further includes: when the status of holding the terminal by the user is the state of holding by the left hand, suppressing the transmit/receive power of the left antenna; or when the status of holding the terminal by the user is the state of holding by the right hand, suppressing the transmit/receive power of the right antenna.

The terminal may increase transmit/receive power of one antenna that suffers less interference, and suppress transmit/receive power of the other antenna that suffers more interference. Therefore, power consumption of the terminal can be reduced while it is ensured that voice communication quality of the terminal is not affected.

In another possible design, to improve efficiency of performing voice communication by the user by using the terminal, the terminal may further adjust volume of a left voice channel and volume of a right voice channel of the terminal based on the status of holding the terminal by the user. After the detecting a current status of holding the terminal by a user in a voice communication process of the terminal, the method in this application further includes: when the current status of holding the terminal by the user is the state of holding the mobile phone by the left hand, turning up the volume of the left voice channel of the terminal; or when the current status of holding the terminal by the user is the state of holding the mobile phone by the right hand, turning up the volume of the right voice channel of the terminal.

If the current status of holding the terminal by the user is the state of holding the mobile phone by the right hand, it indicates that the right side of the terminal is closer to an ear of the user. To enable the user to more clearly hear voice information transmitted from a peer device in the voice communication, the terminal may turn up the volume of the right voice channel of the terminal.

In another possible design, when the current status of holding the terminal by the user is the state of holding the mobile phone by the left hand, the terminal may turn down the volume of the right voice channel of the terminal; or when the current status of holding the terminal by the user is the state of holding the mobile phone by the right hand, the terminal may turn down the volume of the left voice channel of the terminal.

DESCRIPTION OF EMBODIMENTS

The terms “first” and “second” mentioned below are merely intended for description, and shall not be understood as an indication or implication of relative importance or an implicit indication of a quantity of indicated technical features. Therefore, a feature defined by “first” or “second” may explicitly or implicitly include one or more features. In the description of this application, unless otherwise stated, “a plurality of” means two or more than two.

A method provided in an embodiment of this application may be as follows: When detecting that a status of holding a terminal by a user undergoes a change satisfying a preset condition, the terminal automatically displays a control used to start a preset application or a preset function in the terminal; and then in response to a preset operation of the user on the control, the terminal may start the application corresponding to the preset operation or perform the function corresponding to the preset operation; or if the terminal does not detect a preset operation of the user on the control within a preset time after the terminal displays the control, the terminal may not continue to display the control, that is, the control may disappear on a display screen of the terminal.

In an embodiment of this application, a photographing method and a terminal are provided, and the method may be applied to a process of starting a “Camera” application by the terminal for photographing. Specifically, the terminal may detect a status of holding the terminal by a user, and when the terminal displays a first interface, the terminal displays, on the first interface in response to detecting that the status of holding the terminal by the user undergoes a change satisfying a preset condition, a photographing control used to turn on a camera, so that the user can operate the photographing control to start the “Camera” application for photographing. The terminal automatically detects the status of holding the terminal by the user, and displays the photographing control used to turn on the camera, so that the user can operate the photographing control to start the “Camera” application for photographing. This can simplify user operations for starting the “Camera” application on the terminal, improve human-machine interaction performance of the terminal, and further improve user experience.

It should be noted that, the terminal in this application includes the camera and a sensor, and the sensor is configured to detect the status of holding the terminal by the user. For example, the terminal may be a mobile phone (such as a mobile phone 100 shown in FIG. 1 ), a tablet computer, a personal computer (Personal Computer, PC), a personal digital assistant (personal digital assistant, PDA), a smartwatch, a netbook, a wearable electronic device, or the like. A specific form of the apparatus is not specifically limited in this application.

The method provided in this embodiment of this application may be performed by an apparatus for performing the method, for example, a photographing apparatus. The photographing apparatus may be the mobile phone 100 shown in FIG. 1 ; or the photographing apparatus may be a central processing unit (Central Processing Unit, CPU for short) in the terminal, or a control module that is in the terminal and is configured to perform the photographing method. In this embodiment of the present invention, the photographing method is described by using an example in which the terminal performs the photographing method.

As shown in FIG. 1 , the mobile phone 100 is used as an example of the terminal. The mobile phone 100 may specifically include components such as a processor 101, a radio frequency (Radio Frequency, RF) circuit 102, a memory 103, a touchscreen 104, a Bluetooth apparatus 105, one or more sensors 106, a Wi-Fi apparatus 107, a positioning apparatus 108, an audio circuit 109, a peripheral interface 110, and a power source 111. The components may perform communication by using one or more communications buses or signal cables (not shown in FIG. 1 ). A person skilled in the art may understand that, a hardware structure shown in FIG. 1 does not constitute a limitation on the mobile phone. A quantity of components included in the mobile phone 100 may be greater or less than that shown in the figure, or some components are combined, or component arrangements are different.

The following describes each component of the mobile phone 100 in detail with reference to FIG. 1 .

The processor 101 is a control center of the mobile phone 100. The processor 101 is connected to all parts of the mobile phone 100 by using various interfaces and lines, and executes various functions and data processing of the mobile phone 100 by running or executing an application program stored in the memory 103 and invoking data stored in the memory 103. In some embodiments, the processor 101 may include one or more processing units. In some embodiments of this application, the processor 101 may further include a fingerprint verification chip, configured to verify a captured fingerprint.

The radio frequency circuit 102 may be configured to receive and send radio signals. Particularly, after receiving downlink data from a base station, the radio frequency circuit 102 may send the downlink data to the processor 101 for processing, and send uplink data to the base station. Generally, the radio frequency circuit includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, or the like. In addition, the radio frequency circuit 102 may further communicate with another device through wireless communication. The wireless communication may be based on any communication standard or protocol, including but not limited to the global system for mobile communications, general packet radio service, code division multiple access, wideband code division multiple access, long term evolution, or the like.

The memory 103 is configured to store the application program and data. The processor 101 executes various functions and data processing of the mobile phone 100 by running the application program stored in the memory 103 and invoking data stored in the memory 103. The memory 103 mainly includes a program storage area and a data storage area. The program storage area may store an operating system, an application program required by at least one function (such as an audio playing function or an image reviewing function). The data storage area may store data (such as audio data or a phone book) that is created according to usage of the mobile phone 100. In addition, the memory 103 may include a high-speed random access memory (Random Access Memory, RAM), and may further include a non-volatile memory, for example, a magnetic disk storage device, a flash memory, or another non-volatile solid-state storage device. The memory 103 may store various operating systems. The memory 103 may be independent, and is connected to the processor 101 by using the communications bus; or the memory 103 may be integrated with the processor 101.

The touchscreen 104 may specifically include a touchpad 104-1 and a display 104-2.

The touchpad 104-1 may capture a touch event of a user of the mobile phone 100 on or near the touchpad (for example, an operation performed by the user by using any appropriate object such as a finger or a stylus on the touchpad 104-1 or near the touchpad 104-1), and send captured touch information to another component (for example, the processor 101). The touch event near the touchpad 104-1 may be referred to as a floating touch. The floating touch may be that the user does not need to directly touch the touchpad for selecting, moving, or dragging an object (for example, an icon), and that the user only needs to be located near the device for ease of performing a required function. In addition, the touchpad 104-1 may be a resistive touchpad, a capacitive touchpad, an infrared touchpad, or a surface acoustic wave touchpad.

The display (also referred to as a display screen) 104-2 may be configured to display information input by the user or information provided for the user and various menus of the mobile phone 100. The display 104-2 may be configured in a form of a liquid crystal display, an organic light-emitting diode, or the like. The touchpad 104-1 may cover the display 104-2. After detecting the touch event on or near the touchpad 104-1, the touchpad 104-1 transmits the touch event to the processor 101 to determine a type of the touch event. Then the processor 101 may provide a corresponding visual output on the display 104-2 based on the type of the touch event.

It should be noted that, although the touchpad 104-1 and the display screen 104-2 are used as two independent components to implement input and output functions of the mobile phone 100 in FIG. 1 , the touchpad 104-1 and the display screen 104-2 may be integrated to implement the input and output functions of the mobile phone 100 in some embodiments. It may be understood that, the touchscreen 104 may be formed by a plurality of stacked layers of materials. Only the touchpad (layer) and the display screen (layer) are presented in this embodiment of this application. Other layers are not described in this embodiment of this application. In addition, the touchpad 104-1 may be configured on a front side of the mobile phone 100 in a form of a complete panel, and the display screen 104-2 may also be configured on the front side of the mobile phone 100 in a form of a complete panel. Therefore, a bezel-less structure can be implemented for the front side of the mobile phone.

In addition, the mobile phone 100 may further have a fingerprint recognition function. For example, a fingerprint recognizer 112 may be configured on a rear side (for example, below a rear-facing camera) of the mobile phone 100, or a fingerprint recognizer 112 is configured on a front side (for example, below the touchscreen 104) of the mobile phone 100. For another example, a fingerprint recognizer 112 may be configured in the touchscreen 104 to implement the fingerprint recognition function. To be specific, the fingerprint recognizer 112 may be integrated with the touchscreen 104 to implement the fingerprint recognition function of the mobile phone 100. In this case, the fingerprint recognizer 112 is configured in the touchscreen 104, and may be a part of the touchscreen 104, or may be configured in the touchscreen 104 in another manner. A main component of the fingerprint recognizer 112 in this embodiment of this application is a fingerprint sensor. The fingerprint sensor may use any type of sensing technology, including but not limited to an optical, capacitive, piezoelectric, or ultrasonic sensing technology, or the like.

The mobile phone 100 may further include the Bluetooth apparatus 105, configured to implement data exchange between the mobile phone 100 and another short-range device (for example, a mobile phone or a smartwatch). The Bluetooth apparatus in this embodiment of this application may be an integrated circuit, a Bluetooth chip, or the like.

The one or more sensors 106 include but are not limited to the foregoing sensor. For example, the one or more sensors 106 may further include a light sensor, a motion sensor, and another sensor. Specifically, the light sensor may include an ambient light sensor and a proximity sensor. The ambient light sensor may adjust luminance of the touchscreen 104 based on brightness of ambient light. The proximity sensor may turn off the display when the mobile phone 100 moves to an ear. As a type of motion sensor, an accelerometer sensor may detect acceleration magnitudes in all directions (generally tri-axis), and when the accelerometer sensor is stationary, may detect a magnitude and a direction of gravity, and may be used in a posture recognition application of the mobile phone (for example, switching between landscape orientation and portrait orientation, a related game, or magnetometer posture calibration), a function related to vibration recognition (for example, a pedometer or a stroke), or the like. For other sensors that may be configured for the mobile phone 100, such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, details are not described herein.

The Wi-Fi apparatus 107 is configured to provide network access complying with a Wi-Fi related standard for the mobile phone 100. By using the Wi-Fi apparatus 107, the mobile phone 100 may access a Wi-Fi hotspot, and further help the user send and receive e-mails, browse web pages, access streaming media, and the like. The Wi-Fi apparatus 107 provides wireless broadband Internet access for the user. In other embodiments, the Wi-Fi apparatus 107 may also be used as a Wi-Fi wireless access point, and may provide Wi-Fi network access for another device.

The positioning apparatus 108 is configured to provide a geographic location for the mobile phone 100. It may be understood that, the positioning apparatus 108 may be specifically a receiver of a positioning system such as a global positioning system (Global Positioning System, GPS), a BeiDou navigation satellite system, or Russian GLONASS.

After receiving the geographic location information sent by the positioning system, the positioning apparatus 108 sends the information to the processor 101 for processing, or sends the information to the memory 103 for storage. Alternatively, in other embodiments, the positioning apparatus 108 may be a receiver of an assisted global positioning system (Assisted Global Positioning System, AGPS). The AGPS, as an assistance server, assists the positioning apparatus 108 in completing ranging and positioning services. In this case, the positioning assistance server communicates with the positioning apparatus 108 (that is, a GPS receiver) of a device such as the mobile phone 100 to provide positioning assistance.

Alternatively, in other embodiments, the positioning apparatus 108 may use a positioning technology based on a Wi-Fi hotspot. Because each Wi-Fi hotspot has a globally unique media access control (Media Access Control, MAC) address, the device may scan and capture broadcast signals of nearby Wi-Fi hotspots when Wi-Fi is enabled, and therefore can obtain MAC addresses broadcast by the Wi-Fi hotspots; the device sends, to a location server by using a wireless communications network, data (for example, the MAC addresses) that can identify the Wi-Fi hotspots; and the location server retrieves a geographic location of each Wi-Fi hotspot, calculates the geographic location of the device with reference to strength of the Wi-Fi broadcast signals, and sends the geographic location to the positioning apparatus 108 of the device.

The audio circuit 109, a speaker 113, and a microphone 114 may provide an audio interface between the user and the mobile phone 100. The audio circuit 109 may convert received audio data into an electrical signal and then transmit the electrical signal to the speaker 113, and the speaker 113 converts the electrical signal into an audio signal for outputting. In addition, the microphone 114 converts a captured audio signal into an electrical signal, and the audio circuit 109 converts the received electrical signal into audio data and then outputs the audio data to the RF circuit 102; and then the audio data is transmitted to another mobile phone, or the audio data is output to the memory 103 for further processing.

The peripheral interface 110 is configured to provide various interfaces for external input/output devices (for example, a keyboard, a mouse, an external display, an external memory, and a subscriber identity module card). For example, the peripheral interface is connected to the mouse by using a universal serial bus (Universal Serial Bus, USB) interface, or connected, by using a metal contact in a subscriber identity module card slot, to a subscriber identity module (Subscriber Identity Module, SIM) card provided by a telecommunications operator. The peripheral interface 110 may be configured to couple the external input/output peripheral device to the processor 101 and the memory 103.

In this embodiment of the present invention, the mobile phone 100 may communicate with another device in a device group by using the peripheral interface 110, for example, may receive, by using the peripheral interface 110, displayed data sent by another device and display the data. This is not limited in this embodiment of the present invention.

The mobile phone 100 may further include the power source apparatus 111 (such as a battery and a power management chip) supplying power to each component. The battery may be logically connected to the processor 101 by using the power management chip, so that functions such as charge and discharge management and power consumption management are implemented by using the power source apparatus 111.

Although not shown in FIG. 1 , the mobile phone 100 may further include a camera (a front-facing camera and/or a rear-facing camera), a flash, a micro projection apparatus, a near field communications (Near Field Communications, NFC) apparatus, and the like. Details are not described herein.

All methods in the following embodiments may be implemented in the mobile phone 100 having the foregoing hardware structure.

An embodiment of this application provides a photographing method. The photographing method may be applied to a terminal, the terminal includes a camera and one or more sensors, and the one or more sensors are configured to detect a status of holding the terminal by a user. As shown in FIG. 2 , the photographing method includes S201 to S203.

S201. A terminal detects a status of holding the terminal by a user.

The terminal may detect, by using a sensor in the terminal, the status of holding the terminal by the user.

S202. The terminal displays a first interface, and displays a first photographing control on the first interface in response to detecting that a current status of holding the terminal by the user undergoes a change satisfying a preset condition, where the first interface is not a viewfinder interface of the terminal.

The first interface in this embodiment of this application may be an interface displayed when the terminal is in a screen-on state. The screen-on state may include a state of displaying a locked-screen interface by the terminal, a state of displaying a home screen (that is, an interface including a plurality of application icons) by the terminal, a state of displaying a display interface of any application by the terminal, or the like. This is not limited in this application.

For example, the terminal is the mobile phone 100 shown in FIG. 1 . The first interface may be a locked-screen interface 301 shown in FIG. 3A; or the first interface may be a home screen 302 shown in FIG. 3B; or the first interface may be an interface 303 of a “Browser” application shown in FIG. 3C. Certainly, the first interface may also be a display interface of the mobile phone 100 for displaying another application (such as a “WeChat” application or an “Alipay” application). This is not limited in this embodiment of this application.

The one or more sensors in this embodiment of this application may determine, by detecting that the terminal is rotated, or that the terminal moves forward relatively to the user, or that the terminal moves upward relatively to a horizontal line, whether the status of holding the terminal by the user undergoes the change satisfying the preset condition. Specifically, the terminal may detect a motion parameter of the terminal; then determine, based on the motion parameter, whether the terminal is rotated, or whether the terminal moves forward relatively to the user, or whether the terminal moves upward relatively to the horizontal line; and finally determine, based on a determining result, whether the status of holding the terminal by the user undergoes the change satisfying the preset condition. For example, as shown in Table 1, this application provides a table of changes of statuses of holding the terminal.

TABLE 1 Table of changes of statuses of holding the terminal Condition Rotated Moving forward Moving upward Icon status Case of 1 Yes Yes Yes Normally displayed condition 2 Yes Yes Yes, but an A displayed icon is satisfaction amplitude is small, and insufficient transparency is high 3 Yes Yes, but an Yes A displayed icon is amplitude is small, and insufficient transparency is high 4 Yes No, or within an Yes Not displayed anti-jitter range 5 Yes Yes No, or within an Not displayed anti-jitter range 6 Yes No, or within an No, or within an Not displayed anti-jitter range anti-jitter range 7 No Yes Yes Not displayed

Referring to Table 1, as shown in the case 1, when the motion parameter detected by the sensor in the terminal indicates that the terminal is “rotated”, “moving forward”, and “moving upward”, the first photographing control may be normally displayed.

As shown in the case 2, when the motion parameter detected by the sensor in the terminal indicates that the terminal is “rotated”, “moving forward”, and “moving upward, but an upward amplitude is insufficient (that is, the upward motion amplitude is less than a first preset amplitude)”, the first photographing control may be normally displayed but is relatively small, and transparency of the first photographing control is relatively high (that is, transparency of the first control displayed in the case 2 is higher than that of the first control displayed in the case 1).

As shown in the case 3, when the motion parameter detected by the sensor in the terminal indicates that the terminal is “rotated”, “moving forward (that is, a forward motion amplitude is less than a second preset amplitude)”, and “moving upward”, the first photographing control may be normally displayed but is relatively small, and transparency of the first photographing control is relatively high.

As shown in the case 4, when the sensor in the terminal detects that the terminal is “rotated”, “not moving forward, but a forward motion amplitude is within an anti jitter range”, and “moving upward”, the terminal does not display the first photographing control on the first interface.

Likewise, the terminal may determine, based on the cases 5 and 6 shown in Table 1, whether the terminal displays the first photographing control on the first interface, and when the terminal needs to display the first photographing control, determine a size and transparency of the to-be-displayed first photographing control.

It should be noted that, in this embodiment of this application, a method for determining, by the terminal, whether the status of holding the terminal by the user undergoes the change satisfying the preset condition and a determining condition include but are not limited to descriptions in the foregoing embodiment. Other determining methods and determining conditions are not described herein in this embodiment of this application.

In addition, the foregoing determining may occur when neither a front-facing camera nor a rear-facing camera is turned on. In addition, the foregoing determining may occur when it is determined that a current scenario is a non-game scenario, that is, it is determined that the user is currently not playing a game, to exclude possible incorrect determining.

Generally, for example, the terminal is a mobile phone 100 shown in FIG. 4A and FIG. 4B. When the user uses the mobile phone 100 for photographing, as shown in (a-1) in FIG. 4A, the user may pick up the mobile phone 100; then as shown in (a-1) in FIG. 4A to (b) in FIG. 4A, the user may gradually raise an arm until the mobile phone is approximately vertical to the ground as shown in (c-1) in FIG. 4A. In this case, the user may start to take a photo.

For example, in this embodiment, “a current status of holding the terminal by the user undergoes a change satisfying a preset condition” may specifically include: an included angle between a display screen of the terminal and a horizontal screen line is within a preset range after the sensor detects that the terminal is rotated and moves upward.

For example, when the mobile phone 100 displays the first interface shown in FIG. 3C, and the status of holding the mobile phone 100 by the user undergoes a change shown in (a-1) in FIG. 4A to (b) in FIG. 4A to (c-1) in FIG. 4A (that is, undergoes the change satisfying the preset condition), the mobile phone 100 may display the first photographing control on the first interface.

It should be noted that, the change satisfying the preset condition in this embodiment of this application includes but is not limited to the change shown in (a-1) in FIG. 4A to (b) in FIG. 4A to (c-1) in FIG. 4A. Because different users have different photographing habits, the terminal may collect statistics about status change parameters captured by the sensor in photographing processes of most or all users using the terminal, and determine changes of the status change parameters as changes satisfying the preset condition. Therefore, the terminal displays the first interface, and when a change of the status change parameters captured by the sensor in the terminal is a change satisfying the preset condition, the terminal may determine, in response, that a possibility that the user wants to take a photo by using the terminal is relatively high, and may display the first photographing control on the first interface.

For example, the first interface is the interface 303 of the “Browser” application displayed by the mobile phone 100, as shown in FIG. 3C. When the user holds the mobile phone 100 in a gesture shown in (a-1) in FIG. 4A, the mobile phone 100 displays the first interface 303 shown in (a-2) in FIG. 4B. As shown in (a-1) in FIG. 4A to (b) in FIG. 4A to (c-1) in FIG. 4A, the gesture of holding the mobile phone 100 by the user changes, and in a change process of the gesture of holding the mobile phone 100 by the user, the mobile phone 100 detects that the current status of holding the mobile phone 100 by the user undergoes the change satisfying the preset condition. In this case, as shown in (c-2) in FIG. 4B, the mobile phone 100 may display a first photographing control 402 on a first interface 401, and the first photographing control 402 is used to turn on a camera of the mobile phone 100.

It should be emphasized that the first interface in this embodiment of this application is not a viewfinder interface of the terminal. For example, the first interface may be the first interface 401 shown in (c-2) in FIG. 4B, (a) in FIG. 5 , or (a) in FIG. 7 , or a first interface 801 shown in FIG. 8A, or a first interface 803 shown in FIG. 8B.

Optionally, the first photographing control in this embodiment of this application may be displayed on the first interface in a floating manner. The terminal may display, on the first interface in response to a moving operation of the user on the first photographing control, dynamic images of the first photographing control that dynamically moves along a moving track of the moving operation. For example, a position of the first photographing control 402 on the first interface 401 shown in (c-2) in FIG. 4B is different from a position of the first photographing control 402 on the first interface 401 shown in (a) in FIG. 5 .

S203. The terminal displays a second interface on the terminal in response to an operation of the user on the first photographing control, where the second interface is a viewfinder interface of the terminal.

In this embodiment of this application, the operation of the user on the first photographing control may be any one of operations of the user on the first photographing control, such as a tap operation, a double-tap operation, and a touch and hold operation. This is not limited in this embodiment of this application.

For example, as shown in (a) in FIG. 5 , the operation of the user on the first photographing control is a tap operation. After the user taps the first photographing control 402 shown in (a) in FIG. 5 , the mobile phone 100 may display, in response to the tap operation of the user on the first photographing control 402, a second interface 501 shown in (b) in FIG. 5 . The second interface 501 shown in (b) in FIG. 5 includes a viewfinder frame 502, a camera switch key 504, a photographing key 503, and a gallery key 505.

The viewfinder frame 502 is used to display a preview image captured by the rear-facing camera or the front-facing camera of the terminal; the camera switch key 504 is used to trigger the terminal to switch between the front-facing camera and the rear-facing camera to capture an image; the photographing key 503 is used to control the terminal to save the preview image captured by the rear-facing camera or the front-facing camera and displayed in the viewfinder frame 502; and the gallery key 505 is used to view an image stored in the terminal. When a default camera of the terminal is the rear-facing camera, the viewfinder frame 502 may display the preview image captured by the rear-facing camera shown in (b) in FIG. 5 .

Optionally, in S203, when the operation of the user on the first photographing control may be a different user operation such as a tap operation, a double-tap operation, or a touch and hold operation, the second interface may also be a photographing interface in a different photographing mode of the terminal. To be specific, the second interface is a photographing interface of the terminal in a photographing mode corresponding to the foregoing operation. Photographing modes of the terminal may include at least a photographing mode using the rear-facing camera, a self-photographing mode, a panoramic mode, and a video mode. Certainly, the photographing modes in this embodiment of this application include but are not limited to the photographing mode using the rear-facing camera, the self-photographing mode, the panoramic mode, and the video mode. Other photographing modes are not described herein in this embodiment of this application.

Specifically, as shown in FIG. 6 , S203 shown in FIG. 2 may be replaced with S601.

S601. The terminal displays, in response to a second operation of the user on the first photographing control, a viewfinder interface in a photographing mode corresponding to the second operation.

The second operation in S601 is the operation of the user on the first photographing control in S203. The second operation may be a different user operation such as a tap operation, a double-tap operation, or a touch and hold operation. The photographing mode corresponding to the second operation is any one of the photographing mode using the rear-facing camera, the self-photographing mode, the panoramic mode, and the video recording mode.

For example, when the second operation is a tap operation, the second interface may be a photographing interface of the terminal in the photographing mode using the rear-facing camera. The photographing mode using the rear-facing camera is a mode of using the rear-facing camera by the terminal to capture an image. For example, after the user taps the first photographing control 402 shown in (a) in FIG. 5 , the mobile phone 100 may display, in response to the tap operation of the user on the first photographing control 402, the second interface 501 shown in (b) in FIG. 5 . The second interface 501 shown in (b) in FIG. 5 is the photographing interface of the terminal in the photographing mode using the rear-facing camera.

When the second operation is a touching and holding operation, the second interface may be a photographing interface of the terminal in the self-photographing mode. The self-photographing mode in this application is a mode of using the front-facing camera by the terminal to capture an image. For example, after the user touches and holds the first photographing control 402 shown in (a) in FIG. 7 , the mobile phone 100 may display, in response to the touch and hold operation of the user on the first photographing control 402, a second interface 701 shown in (b) in FIG. 7 . The second interface 701 shown in (b) in FIG. 7 is the photographing interface of the terminal in the self-photographing mode. A viewfinder frame shown in (b) in FIG. 7 displays a profile picture of the user. When the second operation is a double-tap operation, the second interface may be a photographing interface of the terminal in the panoramic mode, which is not shown in the figure.

In the photographing method provided in this embodiment of this application, when the terminal is in the screen-on state, and detects that the status of holding the terminal by the user undergoes the change satisfying the preset condition, the terminal displays, on the first interface, the photographing control used to turn on the camera, so that the user can operate the photographing control to start a “Camera” application for photographing. When the terminal is in the screen-on state, and automatically detects that the status of holding the terminal by the user undergoes the change satisfying the preset condition, the terminal displays the photographing control used to turn on the camera, so that the user can operate the photographing control to start the “Camera” application for photographing. This can simplify user operations for starting the “Camera” application on the terminal, improve human-machine interaction performance of the terminal, and further improve user experience.

Further, to prevent the terminal from displaying the first photographing control on the first interface for a long time due to an unintentional operation of the user, the terminal may start timing from displaying the first photographing control. If the terminal does not receive a first operation of the user on the first photographing control within a preset time, the terminal may display the first photographing control that gradually scales down, until the first photographing control is not displayed, that is, until the first photographing control disappears. For example, as shown in FIG. 8A, the mobile phone 100 displays a first photographing control 802 on a home screen 801 including a plurality of application icons. Because no operation of the user on the first photographing control is received within a preset time starting from displaying the first photographing control 802 by the mobile phone 100 on the home screen 801 (that is, the first interface), the mobile phone 100 may display a first interface 803 including a first photographing control 804, as shown in FIG. 8B. In comparison with the first photographing control 802 shown in FIG. 8A, the first photographing control 804 shown in FIG. 8B is smaller.

In this application, after the terminal displays the first photographing control on the first interface, if the terminal does not receive the first operation of the user on the first photographing control within the preset time, it indicates that an action of holding the terminal by the user may be an unintentional operation of the user. To prevent the terminal from displaying the first photographing control on the first interface due to an unintentional operation of the user, the terminal may display the first photographing control that gradually scales down, until the first photographing control is not displayed.

It may be understood that, some time is needed from detecting, by the terminal in the screen-on state, that the current status of holding the terminal by the user undergoes the change satisfying the preset condition, to displaying, by the terminal, the first interface including the first photographing control, and then displaying the viewfinder interface in response to the operation of the user on the first photographing control. However, in some scenarios, the user may want to record some fleeting images, but when the terminal interacts with the user to perform the foregoing operation, the images that the user wants to shoot possibly no longer exist, and user experience is affected.

For this case, in this embodiment of this application, when the terminal may be in the screen-on state (that is, the terminal displays the first interface), the terminal may turn on the camera in the terminal in response to detecting that the current status of holding the terminal by the user undergoes the change satisfying the preset condition, to capture a preview image by using the camera. Specifically, as shown in FIG. 9 , after S201 shown in FIG. 2 , the method in this embodiment of this application may further include S901.

S901. When the terminal displays the first interface, the terminal turns on the camera in response to detecting that the current status of holding the terminal by the user undergoes the change satisfying the preset condition, to capture a preview image by using the camera.

In this embodiment of this application, when the terminal displays the first interface, the terminal may directly turn on the camera in response to detecting that the current status of holding the terminal by the user undergoes the change satisfying the preset condition, and start to capture the preview image by using the camera. In addition, in response to detecting that the current status of holding the terminal by the user undergoes the change satisfying the preset condition, the terminal may display the first interface including the first photographing control. To be specific, when displaying the first interface, the terminal may turn on the camera to capture the preview image, instead of starting to capture the preview image in response to the operation of the user on the first photographing control on the first interface only after the first interface is displayed. Therefore, the terminal can capture images in a time period in which the terminal displays the first interface, receives the operation of the user on the first photographing control, and displays the second interface.

It should be emphasized that, when the terminal displays the first interface, even if the terminal turns on the camera to capture the preview image, a viewfinder frame (the viewfinder frame 502 shown in (b) in FIG. 5 ) of the camera is not displayed on the first interface. In other words, even if the terminal has turned on the camera for viewfinder setting and photographing, because the terminal does not display the viewfinder frame, the user cannot see, on the display screen of the terminal, the image captured or taken by the terminal by using the camera.

Because the terminal has turned on the camera when displaying the first interface, and has captured the preview image by using the camera, the terminal may save, in response to the operation of the user on the first photographing control on the first interface, the image captured by the camera, and display the second interface. In addition, the terminal may enable an image recognition function when turning on the camera. Therefore, when the first interface is displayed, actually the terminal has performed image recognition/analysis on the image captured by the camera. Therefore, an image recognition result can be obtained immediately after the user performs the first operation. This helps increase an image recognition speed, and is particularly helpful for some motion scenarios or snap scenarios. Specifically, as shown in FIG. 9 , S203 shown in FIG. 2 may be replaced with S902.

S902. The terminal saves, in the terminal in response to the first operation of the user on the first photographing control, a first image obtained based on the preview image, and displays the second interface on the terminal.

The first operation in this embodiment of this application may be different from the second operation. For example, when the second operation is a tap operation, a touch and hold operation, or a double-tap operation, the first operation may be a slide-up operation or a slide-down operation of the user on the first photographing control.

For example, the first image may be at least one of preview images captured by the camera or a video image including a plurality of images. The terminal may analyze the preview images captured by the camera, to extract the first image from the preview images captured by the camera and save the first image.

When the first operation is a different operation, the first image may be different image content. For example, when the first operation is a slide-up operation of the user on the first photographing control, the first image saved by the terminal may be an image whose definition is the highest in the preview images captured by the camera; or when the first operation is a slide-down operation of the user on the first photographing control, the first image saved by the terminal may be a video image including a plurality of preview images captured by the camera.

Certainly, the first operation and the second operation may also be the same. A photographing mode corresponding to the first operation is any one of the photographing mode using the rear-facing camera, the self-photographing mode, the panoramic mode, and the video recording mode. When the photographing mode corresponding to the first operation is any one of the photographing mode using the rear-facing camera, the self-photographing mode, and the panoramic mode, the first image includes one or more images in the preview images; or when the photographing mode corresponding to the first operation is the video recording mode, the first image is a video image captured by the camera and including a plurality of preview images.

In this application, when displaying the first interface, the terminal may turn on the camera to capture the preview image, instead of starting to capture the preview image in response to the operation of the user on the first photographing control on the first interface only after the first interface is displayed. Therefore, the terminal can capture images in the time period in which the terminal displays the first interface, receives the operation of the user on the first photographing control, and displays the second interface.

Optionally, to facilitate user operations, the terminal may further identify whether the terminal is currently held by a left hand of the user or held by a right hand of the user, and then display the first photographing control in an area that facilitates the user operations. Specifically, S202 may include S202 a.

S202 a. When the terminal displays the first interface, in response to detecting that the current status of holding the terminal by the user undergoes the change satisfying the preset condition, the terminal displays the first photographing control in a high-frequency touch area on a left side of the first interface if the terminal is held by the left hand of the user, or displays the first photographing control in a high-frequency touch area on a right side of the first interface if the terminal is held by the right hand of the user.

The high-frequency touch area in this application is a touch area in which a frequency or quantity of user operations is higher than a preset threshold on the interface of the terminal. The terminal may determine, by using sensors, whether the terminal is held by the left hand of the user or held by the right hand of the user. For example, the sensors may be light sensors disposed on a left side edge and a right side edge of the terminal. When the terminal is held by the left hand of the user, intensity of light captured by the sensor on the right side edge is weaker than intensity of light captured by the sensor on the left side edge, and the terminal may determine that the terminal is held by the left hand of the user.

For example, as shown in FIG. 10 , it is assumed that the mobile phone 100 is held by the left hand of the user. When the mobile phone 100 displays the first interface, in response to detecting that the current status of holding the mobile phone 100 by the user undergoes the change satisfying the preset condition, the mobile phone 100 may display a first photographing control 1001 in the high-frequency touch area on the left side of the first interface.

In this embodiment of this application, the terminal may display the first photographing control in the high-frequency touch area on the left side of the first interface when the left hand of the user holds the terminal, or display the first photographing control in the high-frequency touch area on the right side of the first interface when the right hand of the user holds the terminal, so that the user can operate the first photographing control more conveniently and comfortably, and user experience can be improved.

Further, the second interface may include a second photographing control. For example, the second interface shown in FIG. 11 may include a second photographing control 1101. The second photographing control may be used to control the terminal to perform photographing, and functions as a photographing shutter, that is, the photographing key 503 shown in FIG. 11 .

It may be understood that, when a touchscreen of the terminal is relatively large, the user cannot conveniently tap the photographing shutter for photographing by using a single hand. In this case, the terminal may display the second photographing control on the second interface, and the user can control, by operating the second photographing control, the terminal to save an image captured by the camera.

Specifically, after S203, the method in this application may further include S1201. For example, as shown in FIG. 12 , after S902 (that is, S203) shown in FIG. 9 , the method in this application may further include S1201.

S1201. The terminal saves, in the terminal in response to a third operation of the user on the second photographing control, an image captured by the camera in response to the third operation.

The third operation of the user on the second photographing control may be a tap operation of the user on a second photographing control 1302 on a second interface 1301 shown in (a) in FIG. 13 , and is equivalent to a tap operation of the user on the photographing key 503 shown in (a) in FIG. 13 .

For example, after the user taps the second photographing control 1302 shown in (a) in FIG. 13 , the mobile phone 100 may save, in response to the third operation of the user on the second photographing control 1302, an image captured by the camera in response to the third operation, and display a display interface 1304 shown in (b) in FIG. 13 . After the terminal responds to the third operation, a photo displayed on an icon corresponding to the gallery key 505 changes from a “girl” 1303 shown in (a) in FIG. 13 to a photo 1305 shown in (b) in FIG. 13 , where the photo 1305 is an image in the viewfinder frame shown in (a) in FIG. 13 .

Optionally, to facilitate user operations, when the left hand of the user holds the terminal, the terminal may display the second photographing control in a high-frequency touch area on a left side of the second interface, or when the right hand of the user holds the terminal, the terminal may display the second photographing control in a high-frequency touch area on a right side of the second interface, so that the user can operate the second photographing control more conveniently and comfortably, and user experience can be improved. As shown in (a) in FIG. 13 , because the user holds the mobile phone 100 by using the right hand, the mobile phone 100 may display the second photographing control 1302 in the high-frequency touch area on the right side of the second interface to facilitate user operations.

In this application, the terminal may display, on the second interface, the second photographing control used to control the terminal to perform photographing, and the second photographing control may be displayed on one side on which the user holds the terminal, so that the user can operate the second photographing control more conveniently and comfortably. This can avoid a problem that a single hand of the user cannot conveniently tap the photographing shutter of the terminal for photographing when the touchscreen of the terminal is relatively large, and can improve user experience.

Further, different operations of the user on the second photographing control may be used to instruct the terminal to perform different operations. For example, the terminal may save, in response to the third operation of the user on the second photographing control, the image captured by the camera in response to the third operation, and switch between photographing modes of the terminal in response to a fourth operation of the user on the second photographing control. The third operation and the fourth operation are different. For example, the third operation may be a tap operation of the user on the second photographing control, and the fourth operation may be a double-tap operation or a touch and hold operation of the user on the second photographing control.

Specifically, after S203, the method in this application may further include S1401. For example, as shown in FIG. 14 , after S902 (that is, S203) shown in FIG. 9 , the method in this application may further include S1401.

S1401. The terminal displays a third interface on the terminal in response to the fourth operation of the user on the second photographing control, where the fourth operation is used to instruct the terminal to switch between photographing modes of the terminal, the third interface is a viewfinder interface of the terminal in a photographing mode corresponding to the third operation, and the fourth operation is different from the third operation.

For example, it is assumed that the third operation is a tap operation of the user on the second photographing control, and that the fourth operation is a double-tap operation or a touch and hold operation of the user on the second photographing control.

In a possible implementation, when the fourth operation in this application is a different user operation such as a double-tap operation or a touch and hold operation, the third interface may also be a photographing interface of the terminal in a different photographing mode. To be specific, the third interface is a photographing interface of the terminal in a photographing mode corresponding to the fourth operation. For example, when the fourth operation is a double-tap operation, the third interface is a photographing interface in the panoramic mode; or when the fourth operation is a touch and hold operation, the third interface is a photographing interface in the self-photographing mode.

In another possible implementation, the terminal may switch between the photographing modes of the terminal sequentially in response to the fourth operation of the user on the second photographing control. For example, the terminal may switch between the photographing modes of the terminal sequentially in a sequence of the photographing mode, the panoramic mode, the self-photographing mode, and the video recording mode in response to the fourth operation of the user on the second photographing control. For example, if the terminal is in the photographing mode currently, the terminal may switch the terminal to the panoramic mode in response to the fourth operation of the user on the second photographing control; if the terminal is in the panoramic mode currently, the terminal may switch the terminal to the self-photographing mode in response to the fourth operation of the user on the second photographing control; or if the terminal is in the self-photographing mode currently, the terminal may switch the terminal to the video recording mode in response to the fourth operation of the user on the second photographing control.

For example, after the user double-taps a second photographing control 1501 shown in (a) in FIG. 15 , the mobile phone 100 may display, in response to the double-tap operation (that is, the fourth operation) of the user on the second photographing control 1501, a second interface 1502 shown in (b) in FIG. 15 . The second interface 1502 shown in (b) in FIG. 15 is a photographing interface in the panoramic mode.

In this application, the terminal may switch between the photographing modes of the terminal in response to the fourth operation of the user on the second photographing control. This improves efficiency of switching between the photographing modes of the terminal by the user, and improves user experience.

Optionally, in this application, as the gesture of holding the terminal by the user changes, the first photographing control may move on the first interface; and as the gesture of holding the terminal by the user changes, the second photographing control may also move on the second interface.

For example, as the gesture of holding the terminal by the user changes, the first photographing control may move on the first interface. As shown in (a-1) in FIG. 16A to (b-1) in FIG. 16A to (c-1) in FIG. 16A, as the user holds and moves the mobile phone 100 upward, as shown in (a-2) in FIG. 16B to (b-2) in FIG. 16B to (c-2) in FIG. 16B, a position of a first photographing control 1601 on the first interface also gradually moves toward a lower bezel of the mobile phone 100 to facilitate user operations.

Optionally, an embodiment of this application further provides a method for photographing in a screen-off state. The method specifically includes the following: A terminal is compatible with an existing operation of lighting a screen, for example, screen lighting implemented by using a physical key or a screen-off gesture such as double-tapping the screen or wake screen on wrist raise. When the terminal detects that a user operation satisfies a preset condition when a camera is in an off state, the terminal displays a camera control on the screen, where the camera control may be displayed on the lit screen, or when an AMOLED or the like may be used to light a part of the screen, the terminal may display only one control of the camera on a screen-off interface, or may display a part, for example, display the camera and other controls such as time or a status bar. In addition, the camera control may be displayed on the current interface in a floating manner. A user may implement operations on the camera control very conveniently by dragging. In addition, a display position of the camera control may change with a current holding status of the user. For example, if the terminal detects that the current status is a right-hand holding state, the terminal displays the camera control in a high-frequency touch area on a right side of the screen of the terminal; or if the terminal detects that the current status is a left-hand holding state, the terminal displays the camera control in a high-frequency touch area on a left side of the screen of the terminal. Detecting the left-hand or right-hand holding state pertains to the prior art, and is not described herein. In response to detecting the operation of the user on the camera control, the terminal displays a viewfinder interface. Specifically, for a specific implementation of the embodiment of the method for photographing in the screen-off state, refer to the method for photographing in the screen-on state. Details are not described again.

This application further provides a control method, the control method may be applied to a terminal including a microphone and a sensor, and the sensor is configured to detect a status of holding the terminal by a user. As shown in FIG. 17 , the control method includes S1701 to S1703.

S1701. A terminal detects a current status of holding the terminal by a user.

For detailed descriptions about S1701, refer to the detailed descriptions about S201 in the foregoing embodiment of this application. Details are not described again herein in this embodiment of this application.

S1702. The terminal displays a microphone control on a screen of the terminal in a microphone-off state of the terminal in response to detecting that a current status of holding the terminal by the user undergoes a change satisfying a preset condition.

It is assumed that when a mobile phone 100 displays a home screen 1801 including a plurality of application icons shown in (a-2) in FIG. 18B, or when a mobile phone 100 displays a locked-screen interface, or when a mobile phone 100 displays a display interface of any application, the microphone of the terminal is not turned on.

The microphone-off state of the terminal in this embodiment may also be that the terminal is in a screen-off state. To be specific, when the terminal is in the screen-off state, the terminal may display the microphone control on the terminal in response to detecting that the current status of holding the terminal by the user undergoes the change satisfying the preset condition.

It should be noted that, in this embodiment of this application, when the terminal is in the microphone-off state, an interface displayed by the terminal is referred to as a first interface. For the first interface, refer to the detailed descriptions about the first interface in S202. Details are not described again herein in this embodiment of this application. For example, as shown in (b-2) in FIG. 18B, the first interface may be a home screen 1802 including a plurality of application icons. The first interface shown in (b-2) in FIG. 18B includes a microphone control 1803. As shown in (b-2) in FIG. 19 , the first interface may be a locked-screen interface 1901. The first interface shown in (b-2) in FIG. 19 includes a microphone control 1902.

Generally, for example, the terminal is a mobile phone 100 shown in FIG. 18 . When the user uses the mobile phone 100 for voice input, as shown in (a-1) in FIG. 18A, the user may pick up the mobile phone 100; and then as shown in (a-1) in FIG. 18A to (b-1) in FIG. 18A, the user may gradually raise an arm until a lower end of the mobile phone 100 shown in (b-1) in FIG. 18A is close to a face of the user. In this case, the user may start to record voice data. For example, in this embodiment, “a current status of holding the terminal by the user undergoes a change satisfying a preset condition” may specifically include: a downtilt of a top of the mobile phone reaches a degree or an included angle between a horizontal direction of the mobile phone and a horizontal line reaches a preset angle after the sensor detects that the terminal is rotated and moves upward (detecting that the microphone of the terminal is close to the face (specifically a lip)).

For example, when the mobile phone 100 displays the first interface (an interface displayed by the mobile phone 100 when the mobile phone 100 is in the microphone-off state) shown in (a-2) in FIG. 18B, and the status of holding the mobile phone 100 by the user undergoes a change (that is, the change satisfying the preset condition) shown in (a-1) in FIG. 18A to (b-1) in FIG. 18A, the mobile phone 100 may display the first interface 1802 including the microphone control 1803. When the mobile phone 100 is in the screen-off state shown in (a-2) in FIG. 19 , and the status of holding the mobile phone 100 by the user undergoes a change (that is, the change satisfying the preset condition) shown in (a-1) in FIG. 19 to (b-1) in FIG. 19 , the mobile phone 100 may display the first interface 1901 including the microphone control 1902.

It should be noted that, the change satisfying the preset condition in this embodiment of this application includes but is not limited to the change shown in (a-1) in FIG. 18A to (b-1) in FIG. 18A. Because different users have different habits of recording voice data, the terminal may collect statistics about status change parameters captured by the sensor in voice data recording processes of most or all users using the terminal, and determine changes of the status change parameters as changes satisfying the preset condition. Therefore, when a change of parameters matching the status change parameters captured by the sensor in the terminal is a change satisfying the preset condition, the terminal may determine that a possibility of using the terminal by the user to record voice data is relatively high, and may automatically display the first interface including the microphone control. In addition, a system or the user may set that the foregoing action should be repeated for several times and then entering a speech recognition state is triggered. It should be noted that, the microphone control in this application may be displayed in a fixed position on the first interface; or the microphone control may be displayed on the first interface in a floating manner, and the terminal may display, on the first interface in response to a moving operation of the user on the microphone control, dynamic images of the microphone control that dynamically moves along a moving track of the moving operation.

Optionally, to facilitate user operations, the terminal may further identify whether the terminal is currently held by a left hand of the user or held by a right hand of the user, and then automatically display the microphone control in an area that facilitates the user operations. Specifically, S1702 may include S1702 a.

S1702 a. The terminal displays the microphone control on a left side of the first interface in the microphone-off state of the terminal in response to detecting that the current status of holding the terminal by the user undergoes the change satisfying the preset condition, or displays the microphone control on a right side of the first interface if the terminal is held by a right hand of the user.

Optionally, if the terminal is held by the left hand of the user, the terminal may display the microphone control in a high-frequency touch area on the left side of the first interface; or if the terminal is held by the right hand of the user, the terminal may display the microphone control in a high-frequency touch area on the right side of the first interface. The high-frequency touch area is a touch area in which a frequency or quantity of user operations is higher than a preset threshold on the interface of the terminal.

For example, as shown in FIG. 19 , when the right hand of the user holds the mobile phone 100, the mobile phone 100 may display the microphone control 1902 in a high-frequency touch area on a right side of the first interface 1901 to facilitate user operations.

S1703. The terminal turns on the microphone in response to an operation of the user on the microphone control.

Specifically, S1703 may include: the terminal turns on the microphone in response to the operation of the user on the microphone control, and enables a speech recognition function.

In addition, the system or the user may set a gesture amplitude, or a feedback such as a haptic feedback, a visual feedback, or an auditory feedback to trigger entering the speech recognition state. To be specific, a prompt such as a visual prompt, an auditory prompt, or a haptic prompt is provided for the user when the microphone is turned on.

In this embodiment of this application, the terminal may display the microphone control in the high-frequency touch area on the left side of the first interface when the terminal is held by the left hand of the user, or display the microphone control in the high-frequency touch area on the right side of the first interface when the terminal is held by the right hand of the user, so that the user can operate the microphone more conveniently and comfortably, and user experience can be improved.

This application further provides a communication method, and the communication method is applied to a terminal including a left antenna and a right antenna. The left antenna is disposed on a left part of the terminal, and the right antenna is disposed on a right part of the terminal. As shown in FIG. 20 , the communication method includes S2001 to S2003.

S2001. A terminal detects, in a voice communication process of the terminal, a current status of holding the terminal by a user.

The current status of holding the terminal by the user includes a state of the terminal being held by a left hand or a state of the terminal being held by a right hand. For the method for determining, by the terminal, whether the terminal is held by the left hand of the user or held by the right hand of the user, refer to related descriptions of the foregoing embodiment of this application. Details are not described again herein in this application.

S2002. The terminal increases transmit/receive power of the right antenna of the terminal when the current status of holding the terminal by the user is the state of holding by the left hand.

S2003. The terminal increases transmit/receive power of the left antenna of the terminal when the current status of holding the terminal by the user is the state of holding by the right hand.

In this application, the left side of the terminal is a side corresponding to the left hand of the user when a screen of the terminal is opposite to the user, and the right side of the terminal is a side corresponding to the right hand of the user when the screen of the terminal is opposite to the user. For example, as shown in FIG. 21 , the terminal is a mobile phone 100. A left side of the mobile phone 100 may be a part corresponding to a dashed-line block 2101, and a right side of the mobile phone 100 may be a part corresponding to a dashed-line block 2102.

In this application, the left antenna of the terminal is an antenna disposed on the left side of the terminal, and the right antenna is an antenna disposed on the right side of the terminal. For example, as shown in FIG. 21 , a left antenna of the mobile phone 100 may be disposed in the part corresponding to the dashed-line block 2101 in the mobile phone 100, and a right antenna of the mobile phone 100 may be disposed in the part corresponding to the dashed-line block 2102 in the mobile phone 100.

It may be conceived that the mobile phone 100 is used as an example of the terminal. In a voice communication process of the mobile phone 100, if the right hand of the user holds the mobile phone 100 in FIG. 21 , the right side (the part corresponding to the dashed-line block 2102) of the mobile phone 100 is closer to an ear of the user than the left side (the part corresponding to the dashed-line block 2101) of the mobile phone 100. In this case, because the right side of the mobile phone 100 is close to the ear of the user, the right antenna of the mobile phone 100 may suffer relatively great interference. In this case, using the method in this application to increase transmit/receive power of the left antenna of the mobile phone 100 may ensure that voice communication quality of the mobile phone 100 is not affected.

Likewise, in a voice communication process of the mobile phone 100, if the left hand of the user holds the mobile phone 100, the left side (the part corresponding to the dashed-line block 2101) of the mobile phone 100 is closer to an ear of the user than the right side (the part corresponding to the dashed-line block 2102) of the mobile phone 100. In this case, because the left side of the mobile phone 100 is close to the ear of the user, the left antenna of the mobile phone 100 may suffer relatively great interference. In this case, using the method in this application to increase transmit/receive power of the right antenna of the mobile phone 100 may ensure that voice communication quality of the mobile phone 100 is not affected.

In the communication method provided in this embodiment of this application, in the voice communication process of the terminal, the terminal may determine the status of holding the terminal by the user; and when the status of holding the terminal by the user is the state of holding by the left hand, considering that the left antenna may suffer relatively great interference, to ensure that voice communication quality of the terminal is not affected, the transmit/receive power of the right antenna may be increased; or when the current status of holding the terminal by the user is the state of holding by the right hand, considering that the right antenna may suffer relatively great interference, to ensure that voice communication quality of the terminal is not affected, the transmit/receive power of the left antenna may be increased.

Further, when the status of holding the terminal by the user is the state of holding by the left hand, the left antenna may suffer relatively great interference; or when the status of holding the terminal by the user is the state of holding by the right hand, the right antenna may suffer relatively great interference. Therefore, if one antenna of the terminal suffers relatively great interference, to reduce power consumption of the terminal, the terminal may suppress transmit/receive power of the antenna. Specifically, as shown in FIG. 22 , after S2001 shown in FIG. 20 , the method in this application may further include S2201 and S2202.

S2201. The terminal suppresses transmit/receive power of the left antenna when the current status of holding the terminal by the user is the state of holding by the left hand.

When the current status of holding the terminal by the user is the state of holding by the left hand, the left antenna may suffer relatively great interference. To reduce power consumption of the terminal, the terminal may suppress the transmit/receive power of the left antenna.

S2202. The terminal suppresses transmit/receive power of the right antenna when the current status of holding the terminal by the user is the state of holding by the right hand.

When the current status of holding the terminal by the user is the state of holding by the right hand, the right antenna may suffer relatively great interference. To reduce power consumption of the terminal, the terminal may suppress the transmit/receive power of the right antenna.

In this application, the terminal may increase transmit/receive power of one antenna that suffers less interference, and suppress transmit/receive power of the other antenna that suffers more interference. Therefore, power consumption of the terminal can be reduced while it is ensured that voice communication quality of the terminal is not affected.

Further, to improve efficiency of performing voice communication by the user by using the terminal, the terminal may adjust volume of a left voice channel and volume of a right voice channel of the terminal based on the status of holding the terminal by the user. Specifically, after S2001, the method in this application may further include S2203 and S2204.

S2203. When the current status of holding the terminal by the user is the state of holding the mobile phone by the left hand, the terminal turns up the volume of the left voice channel of the terminal.

If the current status of holding the terminal by the user is the state of holding the mobile phone by the left hand, it indicates that the left side of the terminal is closer to the ear of the user. To enable the user to more clearly hear voice information transmitted from a peer device in the voice communication, the terminal may turn up the volume of the left voice channel of the terminal.

S2204. When the current status of holding the terminal by the user is the state of holding the mobile phone by the right hand, the terminal turns up the volume of the right voice channel of the terminal.

If the current status of holding the terminal by the user is the state of holding the mobile phone by the right hand, it indicates that the right side of the terminal is closer to the ear of the user. To enable the user to more clearly hear the voice information transmitted from the peer device in the voice communication, the terminal may turn up the volume of the right voice channel of the terminal.

Further, when the current status of holding the terminal by the user is the state of holding the mobile phone by the left hand, the terminal may turn down the volume of the right voice channel of the terminal; or when the current status of holding the terminal by the user is the state of holding the mobile phone by the right hand, the terminal may turn down the volume of the left voice channel of the terminal. Therefore, adverse impact of the voice information transmitted from the peer device on other users in the voice communication process of the terminal can be reduced, and a possibility of hearing content of the voice communication by the other users can be further reduced. This helps protect privacy of the user.

In this application, the terminal may further adjust the volume of the left voice channel and the volume of the right voice channel of the terminal based on the status of holding the terminal by the user, so that the user can more clearly hear the voice information transmitted by the peer device in the voice communication. Therefore, an effect of the voice communication can be enhanced. In addition, the possibility of hearing the content of the voice communication by the other users can be further reduced. This helps protect privacy of the user.

This application further provides a display method, and the display method may be applied to a terminal including one or more sensors. The one or more sensors are configured to detect a motion status of the terminal. The display method includes: a terminal detects a motion parameter of the terminal by using a sensor, and displays an interface of a fitness application when the detected motion parameter indicates that the terminal is in a fitness state of a user. The motion parameter includes at least a parameter captured by the sensor when the user does exercises, such as a parameter captured by the sensor when the user runs, a parameter captured by the sensor when four limbs of the user move or when the user twists the waist, or a parameter captured by the sensor when the user bounces.

It may be understood that, no matter which interface the terminal currently displays, such as the interface 303 of the “Browser” application shown in (a-2) in FIG. 4B, the home screen 1801 including a plurality of application icons as shown in (a-2) in FIG. 18B, the screen-off state shown in FIG. 19 , or the locked-screen interface 301 shown in FIG. 3A, when the sensor captures the foregoing motion parameter, the terminal may display the interface of the fitness application, so that the user can operate the terminal on the interface of the fitness application, and the terminal records motion data of the user in the fitness application. Certainly, when the terminal captures the foregoing motion parameter, the terminal may not display the interface of the fitness application, but directly records the motion data of the user in the fitness application.

For example, it is assumed that when the user walks or stands still as shown in (a-1) in FIG. 23 , a mobile phone 100 displays a locked-screen interface 2301 shown in (a-2) in FIG. 23 . When the user starts to run as shown in (b-1) in FIG. 23 , a sensor in the mobile phone 100 may capture the motion parameter when the user runs. In this case, the mobile phone 100 may search for all applications that are installed in the mobile phone 100 and whose application attributes are sport or fitness or health, and present a search result to the user, for example, display an interface 2302 of the fitness application shown in (b-2) in FIG. 23 . Optionally, the interface 2302 of the fitness application includes a plurality of sports items, such as “running”, “cycling”, and “mountain climbing”. The user may select, from the plurality of sports items, a sports item corresponding to a current sport of the user, so that the terminal can record corresponding motion data in the fitness application. Optionally, the terminal may also first search for applications that are already enabled or applications that are in running states and whose attributes are sport-related, for example, sport/fitness/shaping/health, and present found applications; or after no started sport-related application is found, may search for sport-related applications installed in the terminal; or may search for all sport-related applications installed in the terminal, and arrange a started application in a first position.

In the display method provided in this application, the terminal may detect the motion parameter of the terminal by using the sensor, and may display the interface of the fitness application when the detected motion parameter indicates that the terminal is in the fitness state of the user. The interface of the fitness application can be opened without requiring excessive user operations. In this application, after detecting the motion parameter of the terminal, the terminal may automatically search for all applications that are already installed in the terminal and whose attributes are fitness or sport, and display the applications on a screen, that is, display the interface of the fitness application. Therefore, the user can operate the terminal on the interface of the fitness application, so that the terminal records the motion data of the user in the fitness application. This improves man-machine interaction performance, improves operation efficiency, and further improves user experience.
